Why does the cat scratch behind its ears and shake? - briefly
Cats often scratch behind their ears and shake their heads due to the presence of ear mites or an excessive buildup of wax in the ear canal. This behavior is a natural response to irritation or discomfort caused by these tiny parasites or debris.
Why does the cat scratch behind its ears and shake? - in detail
The behavior of cats scratching behind their ears and shaking their heads is not uncommon, and it can be attributed to several reasons.
One of the primary causes for this action is the presence of parasites, particularly ear mites. Ear mites are tiny insects that infest the inner ear canal, causing intense itching and irritation. The cat's attempts to alleviate this discomfort by scratching and shaking its head can be quite vigorous, leading to noticeable behavioral changes. If left untreated, ear mite infestations can result in significant damage to the ear canal, including inflammation, infection, and even permanent hearing loss.
Another common reason for this behavior is an ear infection. Bacterial or fungal infections within the ear can cause similar symptoms of itching and discomfort, prompting the cat to scratch and shake its head. These infections often produce a foul-smelling discharge that may appear as dark brown or black debris inside the ear. Inflammation and swelling are also common signs of an ear infection, which can be painful for the cat.
In some cases, cats may exhibit this behavior due to allergies or skin conditions. Allergic reactions can cause itching in various parts of the body, including the ears. Atopic dermatitis, a condition characterized by excessive itching and inflammation, is often associated with allergens such as pollen, dust mites, or certain foods. Similar to ear mites and infections, allergic reactions can lead to persistent scratching and head shaking.
Regardless of the underlying cause, if you observe your cat frequently scratching behind its ears and shaking its head, it is essential to consult a veterinarian promptly. A thorough examination, including microscopic analysis of ear debris, will help determine the exact nature of the problem. Treatment options may include topical or systemic medications, depending on the diagnosis. Early intervention is crucial for preventing complications and ensuring your cat's overall well-being.
